Testosterone in humans

Great article, well written and god conclusions of collected data.
How ever I am still curious if creating a “shortage” of sperm and decrease of testosterone by cycles of repeated ejaculations during a short period of time, maybe during the course of hours followed by “rest-days” if that over time would provoke the body to produce more Testosterone and sperm in a response to “progressive overload”.
Since this is the way the body handles a lot other things that challenges it´s system with everything from resistance-training, “repeated skin-abrasion”, bacteria and even some toxins.
CHEERS !

Testosterone makes you angry.  This is probably the most common myth about T. The reality is that there’s no concrete evidence that high testosterone levels cause anger and violent outbursts. In fact, the opposite might be true; low testosterone, not high T, is what causes anger and irritability in men. As discussed above, having low T levels has been linked to depression in men and it just so happens that two of the primary symptoms of depression in men are increased angry outbursts and irritability. So if you’re chronically angry, you might be depressed, and you might be depressed because you have low T. As I mentioned above, I became  less  moody and irritable during my experiment, which I attribute to the boost in my testosterone levels.

Hey Ali, what did you do during the period where you were 17-18 to optimize your hormone production? I’m seventeen and I feel like a late bloomer. I’m pretty thin, at 138 lbs, I’m a 5’8 African American, and my shoulders are about 41 inches around. I want to optimize my hormones in order to hit the maximum height for my genetic potential, grower bigger everywhere, develop a more masculine face ( chisleled jawline, wide jaw, course features, etc). Do you have your personal journal in the form of an article anywhere on the site (Kind of new to the site)? Also, I start a strength program. I’m lifting with my schools football team for 30 mins before soccer practice, but soon I will have a gym membership and do starting strength or Greyskull LP.

This one-two punch of decreasing testosterone and increasing cortisol blunts the status drive. Scientists believe humans, as well as other animals, evolved this response as a survival mechanism. If an animal gets beaten in a status competition, it won’t do him any good to keep fighting over and over just to get squashed again and again. Better to just retreat to his cave, lick his wounds, and live to fight another day. What’s interesting is while the cortisol response to status defeat occurs in both men and women, it’s much stronger in men , particularly when the status is achievement related. We’ll discuss why that is in a later article in this series about the evolution of status.

An animal defending against a predator may engage in either " fight or flight " in response to predator attack or threat of attack, depending on its estimate of the predator's strength relative to its own. Alternative defenses include a range of antipredator adaptations , including alarm signals . An example of an alarm signal is nerol, a chemical which is found in the mandibular glands of Trigona fulviventris individuals. [23] Release of nerol by T. fulviventris individuals in the nest has been shown to decrease the number of individuals leaving the nest by fifty percent, as well as increasing aggressive behaviors like biting. [23] Alarm signals like nerol can also act as attraction signals; in T. fulviventris, individuals that have been captured by a predator may release nerol to attract nestmates, who will proceed to attack or bite the predator.
